[Expansive development of the French regulation of the genetic print files after the recent reforms (Part I)].

French regulations related to "genetic prints" and its later incorporation to an automatized file in the frame of the penal process, initially deserved (1998) a positive judgement due to the guarantees surrounding such techniques, considering that with its use an interference was made with the freedom and rights of the individual. This primary regulation is watching a legislative evolution that brings serious doubts about the current guarantee system. A couple of legal reforms with security as their main axis (2001 and 2003) give more importance to the "genetic print" file by extending the causes in which it starts functioning going against the proportionality that must be observed when freedoms and rights of the individual can be affected.
